An automatic organization into topics for a browsing history. In one embodiment, a system identifies groups of browsing actions as related, and clusters the browsing history (e.g. a web browsing history) into sessions based on heuristics used to determine relationships. Latent semantic analysis can be used to determine the relationships which can be considered topics. User interfaces for displaying or otherwise presenting these sessions can include icons representative of topics, and these icons can have different sizes depending on a frequency of web page visits within a topic. The topics can be displayed in time ranges or in a cover flow view or both time ranges and cover flow view.
